I am having same question exactly, and have found a solution
Do you know your R Server's path?
You are able to find full path easily. If you choose an image file in [Files] tab, open the file on the browser maybe.
And then, type this. That's it.
browseURL("http://yourhost:portnumber/files/yourpath/filename.xlsx")

I saved a dataset in a RDS file on onedrive and made it shareable link. Now, if I use that link to read the file, I got an error.
readRDS(url("https://1drv.ms/u/s!Am3aUTxhPMS8iM4pqe5fUZbiA4m9rw"))
#> Error in readRDS(url("https://1drv.ms/u/s!Am3aUTxhPMS8iM4pqe5fUZbiA4m9rw")): unknown input format
On the other hand, if I download the file from the browser, I copy the link address and I use that one...that works.
Unfortunately, the link address obtained in that way is available only for a limited time (it doesn't work permanently).
I know googledrive and rdrop2 and so I have some workarounds,
but still...I don't understand the logic behind this.
Any help?
I am trying to download the Access file in this website http://hidroweb.ana.gov.br/Estacao.asp?Codigo=2043018 through R. Actually, the page directs to where I should click on a button to download the Access file. But I'll have to download hundreds of files from this page and it will change only the last code. If I do it one by one, I'm gonna spend a lot of time. I will do it with a loop, but firstly I must find out how to download the file.
Anyone could give a hint?
Thanks in advance.
A loop and download.file should do this.
In a web form (aspx) I want to ask the user for the path of a file that needs to be used by one of our team.
At first it was a simple textbox but a lot of people send us wrong path (copy/paste seemed too hard for them).
So I tried to use an input file to be sure the path exists but noticed that the file is then send with the form. As the files can weight hundreds of Mb that was not acceptable.
Then I found a way with Jquery to use the input file to get the path of the file without sending it : it works fine on IE but Chrome translate the path in "fakepath". I understand that it is for security reasons.
So I am again looking for a solution, working on all browser, to get from the user the path of a file (with a specific extension) without him being able to write a wrong path.
I hope someone will have the brillant idea I am unable to find :-).
How about receiving only a few kilobytes of the file data from stream instead of the whole file to ensure the path points to a valid file.
I am developing a .NET intranet site which will enable the user to see a list of files (file details stored in DB) and link to the actual PDF/XML/XLS and open it... kind of like a table of contents for the network.
During data entry, the user enters various data about a document, then browses to the file on the network and selects it using the asp:FileUpload. The codebehind then saves the network path to the DB. There is alot of overhead here because i'm sending the file to the server but never use it.
Everything has been working fine until someone tries to use a large PDF file then I get the dreaded MAXIMUM REQUEST LENGTH EXCEEDED error... So I'm trying to find a solution here... I do not need the actual file.. just the path and filename.
I know not all browsers send the full path but our systems have older browsers so everything is working fine now, but will probably break soon.. which is another reason to find a different solution.
I've looked into Javascript to pull the path but that won't work...
Any other ideas? Other ways to just grab the path and filename? (besides manually typing it in to a Text field)
Thanks,
Todd.
This may help too

In Flex i want to upload a particular file to server form local system.how to do it?
Thanks.
You cannot upload a file without using FileReference.browse() followed by an upload(). If it was possible, that would mean that a webpage can read any file from the user's machine without his knowledge or consent.
Can you even imagine the consequences of that?
You can upload byteArrays though if you are sending some images or texts. http://developer.amazonwebservices.com/connect/thread.jspa?messageID=76422
